Project description:JIB-04 is an inhibitor of Jumonji histone demethylases identified through a cell based screen that measures the reactivation of an epigenetically silenced transgene. The active JIB-04 E-isomer shows selectivity for cancer vs. normal cells affecting both transcriptional patterns and cell viability in a cancer specific manner. H358 lung cancer cells or the patient matched HCC4017 (cancer) vs. HBEC30KT (immortalized normal) lung cell pair were treated with DMSO vehicle or 500nM E-isomer or 500 nM Z-isomer of JIB-04 for 4 h or 24 h and RNA extracted.

Project description:We investigate RNA sequencing analysis revealed that the JIB-04 treatment altered the expression of genes that are involved in the cell cycle, apoptosis, and DNA replication and are also related to several cancers including colorectal cancer. JIB-04 also altered the expression of genes involved in various signaling pathways such as the MAPK signaling pathway, the PI3K-Akt signaling pathway, and the Wnt signaling pathway, which is crucial for the proliferation and maintenance of colorectal cancer cells.
Project description:Our RNA sequencing analysis revealed that the JIB-04 treatment altered the expression of genes that are involved in the cell cycle, p53 signaling pathway, and apoptosis, and are also related to several cancers including hepatocellular carcinoma. JIB-04 also altered the expression of genes involved in various signaling pathways such as the FoxO signaling pathway, the PI3K-Akt signaling pathway, which is crucial for the proliferation and maintenance of hepatocellular carcinoma cells.
Project description:41 lung adenocarcinoma from never-smokers hybridized on Illumina SNP arrays on 13 HumanCNV370-Quadv3 chips. High-resolution array comparative genomic hybridization analysis of lung adenocarcinoma in 41 never smokers for identification of new minimal common regions (MCR) of gain or loss. The SNP array analysis validated copy-number aberrations and revealed that RB1 and WRN were altered by recurrent copy-neutral loss of heterozygosity.The present study has uncovered new aberrations containing cancer genes. The oncogene FUS is a candidate gene in the 16p region that is frequently gained in never smokers. Multiple genetic pathways defined by gains of MYC, deletions of RB1 and WRN or gains on 7p and 7q are involved in lung adenocarcinoma in never smokers. A 'Cartes d'Identite des Tumeurs' (CIT) project from the French National League Against Cancer (http://cit.ligue-cancer.net) 41 samples hybridized on Illumina SNP arrays.
